Clearly you have a very personal interest and I was neither 'preaching' nor intending to argue with you, though you have no idea what I know. I do think your comment is a bit unfair on the scientists who published their research as is the norm, but it was jumped on by the media. That's not their fault, but publicizing their initial findings and success to the wider scientific/research community must surely be right?
I wouldn't blame anyone for travelling anywhere to have whatever treatment they can find for serious medical issues, but wouldn't agree without concrete evidence that objectively the NHS has "failed them". The NHS has hard choices to make and many treatments are hideously expensive. The fact has to be faced that there isn't remotely anywhere near enough money to treat everybody, for everything, immediately, with the latest drugs and treatments, on demand.
Anyway that said, my intention wasn't to start an argument, and I wish you good luck in your own case.
